SN74AC17WBQARQ1

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AC17WBQARQ1 is an automotive-grade hex buffer with Schmitt-trigger inputs manufactured by Texas Instruments. It operates within a supply voltage range of 1.5V to 6V and supports a maximum propagation delay of 8.2ns at 5V with a 50pF load. The device provides continuous ±24mA output drive at 5V, with short-burst capability up to ±75mA. It features AEC-Q100 qualification for Grade 1 (-40°C to +125°C), HBM ESD Level 2, and CDM Level C4B protection. The component is housed in a 14-pin WQFN (BQA) package measuring 3mm x 2.5mm.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package type, as the SN74AC17-Q1 family includes multiple packages such as TSSOP and WQFN. Confirm that the BQA suffix corresponds to the wettable flank variant if AOI compatibility is required. Ensure the selected part meets the specific thermal and electrical requirements for the target automotive environment before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring robust signal buffering in noisy automotive environments. The Schmitt-trigger architecture is essential for cleaning up degraded signals from sensors or long traces. Consider the wide 1.5V to 6V operating range for compatibility with various logic levels. Verify that the output drive current requirements do not exceed the continuous or burst limits defined in the absolute maximum ratings.
